The Identification of Single Phase to Earth Faults in Overhead Lines of Electrical Power Distribution Systems

Service continuity is one of the aspects of greater importance in the definition of the quality of electrical energy. After the electrical energy market liberalization, distributors have moved towards new investments in research, first of all in the field of faults diagnostic. The Authors have already studied the problem of the service continuity and this paper represents the development of the research carried out in the field. The paper presents the extension, to overhead distribution lines, of the new diagnostic approach to identify, locate and characterize the faulty events, made up by the Authors. The proposed methodology must be integrated in an electrical distribution networks manage…

Financial Measures for Supporting Wind Power Systems in Europe: A Comparison between Green Tags and Feed’in Tariffs

Distributed Generation demonstrates to be able to significantly influence the electric power system, bringing considerable benefits to the quality of service and improving the energetic efficiency of the distribution network. In particular, in the last few years, Distributed Generation from renewable energy sources is considerably increased thanks to the many support policies promoted worldwide with the aim of facing the environmental issue and the problem of the permanent rise of prices of the fossil energy. In this contest, after a brief review on the financing strategies carried out in Europe in the last decade for promoting the recourse to renewable energy, the paper presents a comparis…

Study of the safety conditions in an extended interconnection of earthing systems of a MV network during an earth fault on the HV network

Problematiche di sicurezza inerenti il collegamento di impianti di terra di stazioni AT/MT a impianti di terra globali

Proximity effect on bare buried conductors connecting together MV/LV substations’ earth electrodes

A new model for a safety analysis in a system of earthing systems interconnected through bare buried conductors

Earthing System's Design in presence of non-uniform soil

The Authors propose a practical approach for facing the problem of the design of the earthing systems in two-layer soils. The approach is based on the calculation of an equivalent resistivity of the non-uniform soil through which the designer can treat this one as it was uniform. The purpose of the Authors is to provide an innovative simple method and some easy-to-use graphs for an easy earthing systems’ design in two-layer soils.

Dimensionamento di impianti di terra in impianti elettrici con tensione superiore a 1kV: analisi critica della Guida CEI 11-37 Ed. II

A New Mathematical Approach for Faults Identification and Location in Distribution Systems

The paper presents a new methodology for fault identification and location in electrical distribution systems, based on the use of a lumped parameter representation of the faulted line and on a matrix approach. Utilities are quite interested in such items, since the new required quality standards put severe constraints on faults management and clearance.
